So let's talk locks and security

lynx, I think what you are trying to do certainly has some merit.
However, the answers to some of your questions are already in the threads people have suggested to you.

Here in list form (whatever else?) are some answers that do not need to be looked for:

1. Sold Secure Gold cannot be trusted, as possible deference to large companies appears to exist.
   
2. The Sheldon bicycle locking method may not be adequate for major cities like London.
   
3. 16mm U-locks/Chains and thicker appear not to be cut by manually-powered boltcroppers.
   
4. Many thefts are due to incorrect locking procedures.
   
5. Bikes locked with Krytonite Fahg Mini have not been stolen if following normal guidelines.
   
6. OnGuard (Brute) locks appear to have an issue with amount of key cuttings issued.
   
7. Saddle security can be best affected by super-gluing a ballbearing into the nut.
   
8. Newest idea for bike security is motorcycle disc lock alarm, put through chainring (tested by Clefty).
   Excellent if bike is stored in communal halls, or on fire escape, or at work in bike sheds/stands.
   
   

Even if it hasn't, at least research, and innovation (on this forum)
has led to many coming on here to find out more. I feel that what you may want to ask, has already been answered, but not in the form that suits you.

Well we agree on point one, whilst point three we disagree on. The 16mm oxford d lock can be cropped with manual cropers as the lock bit between the D is not that solid. The lock alarm is only useful if you can here it IMO.

What I was looking for is something like foxes google thing or someone that actually testing the locks. Should have a chat to almax and see what I can arrange.

Skully, I stated in the Locks That Work thread, that the Sheldon Locking Method would not suffice in areas of high level bike theft.

First of all, the bike, to the untrained eye (opportunist thieves), looks improperly secured. A very well secured normally is obvious, even from across the street, because the lock goes through at least a wheel AND a major part of the frame. Since the Sheldon Method does not secure the frame, then the vulverable part is the wheel. Rims cannot possibly be as strong of the solid steel section of a u-lock, especially a good u-lock.

To comprehensively defeat the Sheldon Method, all one needs to do is this:

1. Deflate the tyre
   
2. Use a sharpened bolt-cutter to cut through the rim (and maybe a couple spokes).
   
3. Use an extra sharp knife on the tyre, as the bolt-cutter may get stuck on rubber.
   
4. Leave behind mangled rear wheel and tyre, with an undisturbed lock.
   
   

Yes, I have appeared to give away advice to thieves. But this is not so. Any thief walking past a bike that they really want, and it is Sheldon Locked, will have the bike in a minute, if carrying a sharpened boltcutter at that time. All he would have to do is try it. It would work immediately. Yes, they will leave behind the rear wheel, but if they've stolen a Mercian or a Pinarello, then it would be worth it to them.

As I have said before, it is fine for provincial security, but not in major cities, or where there is high-level bike theft.

No information that is not known to the thieves.
